This post focuses on custom queries that  allow you to perform additional tasks in Active Directory

Microsoft in Active Directory Users and Computers (ADUC) is a wonderful tool and is very useful when it comes to managing user / and computer accounts in your Domain.  It also has another feature which doesn’t get used often.  The feature I refer to is the ability to use Lightweight Directory Access Protocol (LDAP) queries, saving them for later use.  These queries can be exported and shared by other administrators to find out day to day info such as expired user account, users with accounts locked out, etc.  You can locate this in ADUC under Saved Queries


Go to Active Directory Users and Computers:
Right click the Saved Queries folder and select New, Query.
Enter an appropriate Name and Description.
Make sure the query root is set to the domain level you want the query to pertain to.
Select the Include sub-containers check box if you want the query to search all sub-containers.
Click Define Query.
In the Find dialog box, click the Find drop-down arrow and select Custom Search.
On the Advanced tab, enter your LDAP query string into the Enter LDAP query box.
Click OK twice.

Here are some saved queries I have used

Users that have been given dial-in permissions

Users whose accounts are disabled

Users that must change password at next logon

List all groups that start with IN or SA
